For CONUS beams sure, but not everyone has spotbeam capacity on 101 for their locals. Thus the need for MPEG-4 only markets and equipment.
In fact since UNC is not a national channel I'm not even sure how the MPEG-4 "Greenville Washington New Bern NC market" is receiving an MPEG-2 SD spotbeam from 101 unless its one intended for another market overlapping that one.
Sorry... I didn't check the LiL TPN Map, but given the size of NC, my assumption was that the spot-beam most likely covered, if not the entire state, then most of it.
I'm almost on the complete other side of the state of Georgia, yet I get a 100% on the Atlanta spot-beam from 101°. I get a VERY good signal from the Atlanta HD spot-beam too, but obviously not as strong as the TPN. I was actually talking about the Atlanta HD spot-beam yesterday.
